Keeley Neutrino Envelope Filter overview

  • 1Description

Keeley's Neutrino Envelope Filter Pedal enables you to get funky with its dynamic wah effect. The envelope filter analyzes the input signal using an opto-coupler and based on how hard you pick, the pedal will respond with a wah sound in kind. Guitarists from Jerry Garcia to Guthrie Govan have been known to use this effect to dynamically enhance rhythm and lead playing. Use the onboard controls to tailor the wah sound for your setup.


Gain: Controls the input level of the circuit, this is used to match different sources
Filter Band Selector: Select between L (low-pass) which cuts the treble frequencies, B (band-pass) which emphasizes the midrange, or H (high-pass) to filter out lower frequencies
Range Switch: Adjusts the operating range of the filter selected by the Band Selector switch, Lo emphasizes the lower register, while Hi accentuates higher notes
Peak: Controls the filter frequency, higher settings introduce more energy and resonance to the filter, lower settings offer a mellower sound
Drive Switch: Changes the direction of the filter (think of the way the wah pedal would move after the note is played)
